Standard engineering drawings
The Local Government Association of Tasmania publishes two sets of documents for works on public assets or to create new public assets (roads, footpaths, stormwater infrastructure and others). One set of documents, the Subdivision Guidelines, are for use in a subdivision context. The other set of documents, the Tasmanian Municipal Standard – Specifications along with the Tasmanian Municipal Standard – Drawings (which are to be read together) are for works outside the subdivision context. Both sets of documents can be accessed from the Local Government Association of Tasmania website.
The City of Hobart expects that all drawings and specifications for public assets will meet these standards. There are some departures from the standard drawings which are required by the City of Hobart. View the City of Hobart Departures from LGAT Standard Drawings(PDF, 696KB).
Rather than providing strict prescriptive requirements, the drawings only provide the minimum requirements. The intention of the standard drawings is that they are integrated into the design at hand, allowing greater flexibility to meet site-specific requirements. The designer will remain fully responsible for all aspects of their design and to ensure that designs comply with all the relevant Australian Standards and other regulations.
Road design should also be in accordance with Austroads guidelines.
Design drawings for road geometry and drainage are available directly from the IPWEA website. Please read their advice before you use the drawings.

Three specifications are included in the Tasmanian Councils' Standards for Subdivisions.
You can also access and print the Department of State Growth's Roadworks Specifications from the Transport Services' contractor and industry information webpage.
Signs located over the highway reservation must have minimum clearances as follows:
- 2.4 metres from the underside vertically above footpath level
- 0.6 metres from its outer edge horizontally behind face of kerbline.
It is possible that you will need planning approvals for any new or altered signs. Please check with our Duty Planner on 03 6238 2711.
Condition of use
The specifications and drawings were prepared to assist in the design and construction of municipal road and hydraulic infrastructure. The documents are designed to be used in conjunction with each other and under the supervision of City of Hobart officers who are trained and experienced in their application. We do not consider the documents suitable for use for any other purpose.
If you use these documents for any purpose that is not consistent with the above (including, without limitation, for carrying out any investigations, design, construction, engineering, maintenance or other work), you do so at your own risk.
The drawings only provide the minimum requirements. It is the responsibility of the designer to ensure that designs comply with all the relevant Australian Standards and other regulations.
It is the responsibility of the designer and the developer to ensure that safe construction methods are used and that the construction work complies with the approved design drawings and all the relevant standards and regulations.
